text: Another way to see which is reputable or not, besides the impact factor, is the Editorial Board. Which of these journals have, in your opinion, the strongest Ed.B. (measured by expertise/fame etc). Journals with stronger Ed.B. will guarantee better visibility of your result and, probably, more technical/specialized review process.
  
  You should also know that IF is, sometimes, artificial in the sense that it does not capture the exact quality of the journal. In my field, TCS, there are many highly ranked journals (for example Combinatorica) the impact factor of which is less than many mediocre journals. But does it mean anything? No.
  
  Also, more specialized journals (and hence with lower IF, although that's not always the case) have better visibility on your own field. Submitting your paper in a general purpose journal includes the risk of your paper getting "lost" in otehr unrelated, or borderline related, papers which means high risk of being overlooked by potential readers. You might say that this can be solved by posting it on ArXiv but I found out many interesting papers for my research the way I described above.
  
  At the end of the day, nobody is scrutinizing IF: what matters is how reputable and well known the journal is and how easy or hard is to publish there.
